Motorola is asking the ITC to investigate RIM and bar the company from importing, marketing and selling products in the U.S. that use the technologies.

RIM has been deploying delay tactics in ongoing patent litigation and has refused to design around Motorola’s technologies, Motorola claims.

The companies have been engaged in patent infringement suits dating back to early 2008. In one of those suits, RIM accused Motorola of charging exorbitant fees to license patents that are essential to implementing standard technologies. RIM also accused Motorola of infringing nine of its patents.
